ABSTRACT:
A rod-shaped weighing cell (1) for a vertical compression load sensing having spherically formed and/or plane load application end surfaces (2, 3) has in the center areas (19) or recesses (19) or a cross-bore (4) to which strain gages (9) are attached. The crossbore, or areas, or recesses or is closed at both ends or covered with a metallic cover (7, 8) the edges of which are sealed e.g. welded to the weighing cell body 1A). One cover disk (7) is provided with a screw connector (10) for a lead-through of a cable (11) which is connectable to the strain gages (9). The cover disk is just large enough to enclose and seal the strain gages without enclosing or encircling the entire load cell body.
